CABLE OR ROPE.

Specification of Letters Patent.

Application filed Iuly 2.1906. Serial No. 3244436;

To all whom it may concern.' 4

Be it known that I, GIULIO MAGALDI, a subject of the King of Italy, residing at Buccino, near Salerno, in the JKingdom of Italy, have invented new and useful Improvements in Cables or Ropes, of which the following is a specification.

The present invention relates to a cable or rope made of homogeneous organic substances, particularly of leather, skin or the like. The cable is held together by suitably provided inwardly arranged preferablyv metallic clamps. In such a cable the deformation and diminution in cross section is avoided, to which the cables used up to the present, and made of vegetable or animal substances are subject. This is particularly the case with cables made of twisted fibers. It is characteristic of the present invention, that it will serve for the manufacture of cables or ropes of various form, say of round, rectangular, square or irregular section.

In the accompanying drawings, Figure 1 represents a transverse section of one form of this improved cable Fig. 2 represents a transverse section of another form thereof Fig. 3 represents a side elevation of the cable partly in section 5 Fig. el. represents a plan view of one of the spiders used in the construction of the cable 3 Fig. 5 represents a side elevation of the spiders connected, Fig. 6 represents a longitudinal section of a modiied form of cable 5 Figs. 7 and 8 represents longitudinal sections through parts of modiiied forms of the cable showing another form of connecting means for the spiders, the ifigures differing only in the number of spiders forming the several groups. Figs. 9 to `13 show details of the various connecting parts.

The cable or rope consists of strips (L, laid along the longitudinal axis of the cable and held together by thc inwardly arranged clamps. Figs. l and 2 being sectional views show the manner in which these strips are placed over each other Fig. 3 shows the arrangement in front-view and longitudinal section.A This arrangement is important, so much the more as the bending and twisting stresses, to which the cable is subjected, will greatly affect the sides and edges -bof each single strip, whereas the composite texture of which the leather consists, is not subjected to a sul'liciently heavy strain, to cause deformation, so that the inward struct-ure of The single strips are Without longitudinal gaps, and are in contact with each other on a great part of their surface. By the extent of the surface and by the relative position of the single parts all possibility of tearing owing to alternate action of neighboring parts is avoided.

The connecting medium proper is formed by spiders with four, six or more prongs (see Figs. 4 and 13) the various strips of the belt being wound around or interlaced between these prongs. The number of the prongs depends on the shape of the cable. (')f these spiders at the least two each are combined, (see Figs. 5, 6 and 7); often however also four (see Figs. 3 and S) or even six or more.

Plates or washers *d- (Fig. 9) having holes -eare intended to be placed on the prongs of the strips. The points of these prongs penetrate the breadth of the leather strips or the like and are thereupon bent over at the edges on the outside of the leather strips, as shown in the above said figures, whereby they are forced as deep into the leather as required.

The spider-shaped parts which are preferably employed in pairs, (see Fig. 7), but which may be used in greater numbers if desired, are arranged adjacent to each other and connected together in groups by the washers hereinbefore described. -(Sec Fig. 8.) In this case the single spiders may be employed to hold. the various strips of the cable in different zones, that is to say, the points of sonic of the spider prongs may be bent down before totally penetrating all of the spiders, while the points of others may be bent after having penetrated the outer layers of the strips. 'lhc washers can also be made as shown in Fig'. 10, and cach set of spiders can be locked to thc next one (see Figs. 2 and 6) in which instance the spiders of each set can besides be held together by means of small washers f (Fig. 1]).` A. set of spiders may also be locked together by bolts g which extend through central openings in the spiders, being preferably strengthened at their ends to prevent the bolts from slipping out of said holes. The strengthened ends of the bolt g have their inner faces tapered and form a very flexible connection'between the adjacent sets of spiders. In the designs shown in Figs. 3 and 6 the clamping device forms a regular chain, which will besides give a certain strength to the cable or rope. The designs shown in Figs. 7 and S on the other hand are remarkable for their great iiexibility.

The designs shown of the present invention are merely intended to exemplify the mode of carrying out the latter, the means of holding the parts together can be of any other type, without alteration to the character of the invention.

Having now described my invention what I claim and desire to secure by Letters Patent of the United States is:

l. A cable of the class described Comprising longitudinal strips and spiders having radial arms to which the strips are secured.

2. A cable of the class described comprising longitudinal strips, and spiders having radial arms extended through and fastened to said strips.

3. A cable of the class described comprising longitudinal strips, and spiders having radial arms, said strips being laced between and around said arms.

4. A cable of the class described comprising longitudinal strips, and spiders having radial arms to which the strips are secured by binding over the ends of the arms.

5. A cable of the class described comprising longitudinal strips, spiders having radial arms to which the strips are secured, and washers on said arms bearing against the inner sides of the strips.

6. A cable of the class described comprising longitudinal strips, spiders having radial arms secured to said strips, and means independent of said strips, connecting the spiders together.

7. A cable of the class described comprising longitudinal strips, spiders having radial arms to which the strips are secured, and washers on the corresponding arms of two adjacent spiders, said washers being connected by a plate.

8.' A cable of the class described comprising longitudinal strips, spiders having radial arms secured to said strips, and means independent of said strips connecting the spiders together for angular movement with respect to one another.

9. A cable of the class described comprising longitudinal strips, and spiders having radial arms secured to said strips, said spiders being arranged in groups of two or more.

10. A cable of the class described comprising longitudinal strips, spiders having radial arms secured to said strips, said spiders being arranged in groups of two or more, and washers on said arms connecting them together and bearing against the inner sides of said strips.

11. A cable of the class described, comprising longitudinal strips, spiders arranged in groups and having radial arms secured to said strips, and means independent of said strips for connecting neighboring spiders and groups of spiders together.

f12. A cable of the class described comprising longitudinal strips, spiders having radial arms secured to said strips, said spiders being arranged in groups, and Washers on said arms, two opposite washers of neighboring spiders or groups of spiders being connected.

13. A cable of the class described comprising longitudinal strips, spiders having radial arms secured to said strips, said spiders being arranged in groups, links provided with holes, said links being arranged with the holes therein engaging the arms of neighboring spiders or groups of spiders, some of said links connecting the spiders to their preceding neighboring spiders, the other of said links connecting them to their following neighboring spiders.

14. A cable of the class described comprising longitudinal strips, spiders having radial arms secured to said strips, said spiders being arranged in groups, washers on said arms connecting them together and bearing against the inner sides of said strips, and means independent of said strips for connecting two neighboring spiders or groups of spiders together, as described.

15. A cable of the class described comprising longitudinal strips, spiders having radial arms secured to said strips, said spiders being arranged in groups of two or more, washers on said arms to hold them together, said washers bearing against said strips, links bearing aga-inst the inner sides of said strips, said links having holes therein, engaging the arms of said spiders, some of said links being attached to a spider connecting it to the preceding spider, the other of said links connecting it to the following spider.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
